Nice pic Monster.

I have a GZ32 Mullard in my EL3N amp as a rectifier right now, but have not listened my amp much because of being sick....maybe tonight I will get some listening time.

The HD250 looks interesting, I know nothing about it....what is its sound signature like ?

Hope you feel better.
It's a very balanced sound with great extension on both ends, digs down deep.
Tonally solid very wide and deep staging especially for a closed back.
Sennheiser announced they're bringing it out of retirement, but not many details have surfaced yet .
There's a dedicated HD250 thread, should be on the first page in headphone section.
IMO it's the biggest sleeper headphone I have heard, and it scales very well, as I'm learning.

Its a great all-arounder,enjoy it much more than HD650/6xx

Thanks for all of the info.

Sittard/Holland GZ34 in the house! I have been listening to it for the last 3 hours and it is super addictive, this really brings the the EL3N up a few notches. I have another Mullard GZ32 which I still have not tried.

Are those EL6 you are using for outputs?? How does it sound with the EL6?

Yep, those look like EL6 to me also...wondering the same...how do they sound.

Yup, those are EL6. They sound really similar to the EL3N (clean, dynamic, great vocals, punchy bass & sub bass) but I feel they add slightly more body to the sound. I use slightly less gain when driving the Abyss Phi.

GZ34 + EL3N + EL6 + Abyss Phi = Audio bliss..

All of the sudden I now have the following tubes:

- 8 x EL3N
- 2 x EL3 (straight bottle)
- 4 x EL6
- 1 x Sittard/Holland Philips GZ34
- 1 x Mullard GZ32 brown base
- 1 x 3DG4 (came with the amp)

I’ll stop the tube spree at such but will still be on the look out if something special comes along.

I have the GZ32 in my amp at the moment and it sounds very good also.

I may at some time try a pair of EL6

I would expect the GZ32 to have a warmer/tubish signature?

 

[whirlwind]

I do not have a GZ34...but you hit the nail on the head as far as the sound of the GZ32

Warm, no hint of any brightness, yet very, very detailed.

If there is a better 81 year old player...I want to hear him. Epic album.

Agree with the description of the sound of the EL6 (which sounds similar to the EL12 which uses a different base).
What's left to explore is the EL54:

and maybe some EL side contact variants with anode caps such as the Telefunken EL6 Spez:

What is intriguing is that the EL12 Spez is considered superior to the EL12.
Did anybody compare the Telefunken straight glass EL3 tubes to the ST EL3N?

Guess there are more tube rolling options with the EL3N amp then I originally thought.

Could the EL3N handle this?

Probably would work but no tube base available to make a adapter with the anode lead.

Thanks for your description on the GZ32.

Treble on the GZ34 sounds smoother (but not rolled off) when compared to the 3DG4.
